Login attack on cyrus imap

[Jim John]

I found out that it was a single IP from the log
files. That person (or bot) logs into the POP3 server
and tries to authenticate itself. The problem is that
it logs in as a different user each time and does ALOT
of these logins per second, causing LDAP to overload
with connections. Is there any way to limit the number
of connections in the cyrus server using some config
parameter? Thanks.
